Abstract
The utility model relates to a high-speed switch valve for a vehicle suspension system, comprising a valve body (1), an oil inlet, an oil outlet and a valve core, wherein the valve body (1) is internally provided with a movable iron core chamber that is internally provided with a movable iron core (2); the oil inlet and the oil outlet are arranged at the end part of the valve body (1); the valve body (1) is internally provided with a valve core chamber that is internally provided with the valve core (3) which is connected with the movable iron core (2); and a return spring (4) is arranged between the valve core (3) and the valve core chamber. The high-speed switch valve mainly consists of the valve core, the movable iron core and the valve body and is a two-way normally-closed electromagnetic valve. When an electromagnet is not electrified, the valve core can cut off the oil inlet and the oil outlet; when the electromagnet is electrified, the valve core moves to the right, and the oil inlet and the oil outlet can be conducted; and the valve core can recover by the spring after the electricity of the electromagnet is cut off. The movable iron core chamber is communicated with the oil outlet so as to ensure that the movable iron core can move at high frequency, thereby ensuring the frequency response of the high-speed switch valve.
Description
Technical field
The utility model relates to the control unit in a kind of switch type semi-active suspension system, and is used to lay down the high-speed switch valve that dydraulic shock absorber quickens the damping force of cross-car vibration.
Background technique
The performance of the control unit in the half switch type semi-active suspension system has determined the success or failure of switch type semi-active suspension system, the main effect of high-speed switch valve in the switch type semi-active suspension system makes off-load, promptly lay down dydraulic shock absorber and quicken the damping force that cross-car is vibrated, high-speed switch valve in the switch type semi-active suspension system relates to several factors, mainly comprise pressure, flow, frequency of okperation and operating temperature, existing switch valve can not satisfy the requirement of its speed-sensitive switch, because its specific conditions requirement, it is very necessary to design and develop a kind of high-speed switch valve that is used for vehicle half switch type semi-active suspension system.
The model utility content
The purpose of this utility model is the shortcoming at prior art, and a kind of reasonable in design is provided, and can guarantee the high-speed switch valve of frequency response.
The technical solution of the utility model is: a kind of vehicle suspension system high-speed switch valve, comprise valve body, filler opening, oil outlet and spool, the inside of described valve body is provided with moving iron core chamber, moving inside, iron core chamber is provided with moving iron core, the end of valve body is provided with filler opening, oil outlet, and inside is provided with spool chamber, is provided with spool in the spool chamber, spool and moving iron core join, and are provided with Returnning spring between described spool and the spool chamber.
Preferably: described high-speed switch valve is two to close solenoid valve usually.
The beneficial effects of the utility model are: the utility model mainly is made up of spool, moving iron core and valve body, is two to close solenoid valve usually.Electromagnet not under the electric situation, spool cuts off filler opening and oil outlet, gets under the electric situation at electromagnet, spool moves to right, filler opening and oil outlet conducting, the outage back valve core passes through spring reset.Moving iron core chamber and oil outlet conducting have guaranteed that moving iron core can move on high frequency ground, can guarantee the frequency response of high-speed switch valve.
